Effects of Second-Season Crops on Soybean Cultivation in Compacted Soil in Brazilian Cerrado

In no-tillage systems, soil compaction has caused negative impacts on crop productivity and quality. The objective of this study was to evaluate the physical quality after different crops second season: maize, sorghum, millet in compacted uncompacted soils, addition evaluating performance soybean succession Rhodic Ferralsol under (NT) Brazilian Cerrado biome. A field experiment conducted during season 2019 first 2019/20 Rio Verde, Brazil. experimental design used randomized blocks a 3 × 2 factorial scheme, with six replications. factor corresponded cultivation millet; these soils. properties soils 0–0.1 0.1–0.2 m depth layers were evaluated cultivation, agronomic characteristics cultivated succession. results indicate that influenced quality, mainly layer, reflecting decrease (i.e., plant height, number pods per plant, grain yield). use second-season improved penetration resistance macroporosity water/air relation. provided reduction up 20% resistance. About 10% more produced compared maize sorghum.
